On-chip memory pairs 32 KB of flash with 4 KB of SRAM, sized for small-footpoint firmware that runs a single control algorithm plus a communication stack over I²C, SPI, or UART. ## Analog front-end and peripheral mix Eight 12-bit SAR ADC channels and two current-output IDACs let the part handle analog sensor conditioning and closed-loop drive without an external converter — the ADC samples at up to 1 Msps, and the IDACs can source or sink up to 2 mA per channel for sensor excitation or feedback trimming. The 36 GPIOs map to a 48-LQFP package (7x7 mm), giving enough I/O for a keypad matrix, LED indicators, and a parallel LCD interface alongside the serial peripherals.","metaTitle":"Infineon CY8C4245AZI-473 PSoC 4 MCU, 48 MHz, 32 KB Flash","metaDescription":"Infineon CY8C4245AZI-473 PSoC 4 ARM Cortex-M0 MCU, 48 MHz, 32 KB flash, 4 KB RAM, 8x12b ADC, 2x IDAC, -40°C to 85°C, 48-TQFP.
